This method was formalized in 2003 and patented after two years of investigation, with the patent expiring in 2005. The objective of the book is to present this method through numerous concrete examples. It covers the theory and principles of instrumentation, explaining how vibratory responses are analyzed to calculate the free and total lengths of the tie rod, as well as its diameter, which includes the reinforcement and its grout. The data obtained from this method can be utilized to:\u003c\/p\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003eVerify that tie rods adhere to drawings\u003c\/li\u003e\r\n\t\u003cli\u003eResize tie rods\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003eA notable strength of this book lies in demonstrating the relationship between dynamic stiffness and the tension force of the tie rod, along with the calibration method using static tensile tests. However, performing static tensile tests at heights poses difficulties due to equipment weight, and there is a genuine risk of failure, especially for older tie rods. The book addresses important aspects such as the uncertainty of results and sampling.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe examples provided in the book primarily stem from tests conducted in Brazil, where more than 2,000 tie rods were tested over a two-year period on motorway and railway retaining walls. In practical terms, this amounts to 16,000 non-destructive tests as each tie rod is tested eight times. These aging structures, in existence for several decades, exhibit load losses ranging from 1% to 5.5% per year during these periods. The book acknowledges the observation of cyclic load effects on these reinforcements, which warrant further investigation.\u003c\/p\u003e\r\n\r\n\u003cp\u003eIn one of the tested walls, a limited number of tie rods were re-tensioned. Retaining wall managers increasingly employ this method for maintenance diagnostics. It allows for a representative sample to be taken, providing insight into the existing conditions.\u003c\/p\u003e\r\n\u003c\/div\u003e\u003cdiv\u003e\n\u003cp\u003eJean-Jacques Rincent\u003cbr\u003e24\/02\/1949\u003cbr\u003eDoctor of Civil Engineering (INSA of Toulouse)\u003c\/p\u003e\n\u003cp\u003eJuly 1993 \/ Present:\u003cbr\u003eChairman of Rincent BTP Services\u003cbr\u003e4 bis rue du Bois Briard\u003cbr\u003e91080 COURCOURONNES\u003cbr\u003e210 employees, including 30% engineers\u003cbr\u003e€19.5 million turnover\u003cbr\u003eANRT - Former member of the board of directors\u003cbr\u003eResearch and development:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNon-destructive testing: Ground anchors, Radar for pavements\u003c\/li\u003e\n\u003cli\u003eProcedure for analyzing the bitumen content of asphalt mixes\u003c\/li\u003e\n\u003cli\u003ePortable Dynaplaque\u003c\/li\u003e\n\u003cli\u003eElaboration of a stripping procedure linked to the calculation of the dynamic stiffness with the University of Evry-Saclay\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eApril 1983 \/ July 1993:\u003cbr\u003eDirector of the Geomechanics Department at the Experimental Center for Building and Public Works\u003c\/p\u003e\n\u003cp\u003eSeptember 1981 – April 1983:\u003cbr\u003eAssociate Assistant Professor, Polytech Lille, Civil Engineering section\u003c\/p\u003e\n\u003cp\u003eDecember 1974 \/ September 1981:\u003cbr\u003eFrench Ministry of Cooperation, teacher at the Civil Engineering Department of the National Engineering School of LIBREVILLE, Gabon.
